Japanese stock futures extended losses after the central bank issued a statement that it kept bond purchases unchanged.
Nikkei 225 Stock Average futures traded at 14,660 in Singapore as of 11:52 a.m. in Tokyo. Before the Bank of Japan announcement, the Nikkei 225 lost 1.1 percent to 14,641.61 at the trading break in Tokyo. The broader Topix index slid 1.6 percent to 1,177.38.
The central bank left unchanged a 60 trillion yen to 70 trillion yen target for yearly expansion of the monetary base.
Forty-four percent of economists in a Bloomberg News survey before the policy decision forecast the BOJ will expand monetary stimulus in July. Analysts polled said the bank will probably double ETF purchases in its next round of easing.
The Japanese central bank increased a growth funding facility to 7 trillion yen at its meeting in February and said individual banks could borrow twice as much low-interest money as previously under another lending program. The Topix jumped the most in five months after the announcement.
